Not sure if this will help, but with my USB-C monitor the default brightness/contrast is poor, and requires manually fiddling with the settings on every boot/resume from sleep, so I found a Linux utility that does the fiddling for me: cat ~/bin/brightness #!/bin/bash # echo "increasing brightness/contrast of external monitor" /usr/local/bin/ddcutil --display 1 setvcp 10 40 /usr/local/bin/ddcutil --display 1 setvcp 12 10 Tie the above in with your init/resume scripts and you're good to go (assumes that your issue isn't limited by the hardware itself).
